Title:
DRYING DEVICE
Document Type and Number:
Japanese Patent JP2004044874
Kind Code:
A
Abstract:
To provide a drying device capable of efficiently evaporating water by heating a drying object.
This drying device is provided with an internal heating rotary kiln 10 fed with the drying object and a combustion device 22 to supply heat air to be a heating source, and heats and dries the drying object by heat of heat air introduced into a rotary kiln 12. In a flow passage in which mixed fluid of water vapor and heat air generated within the rotary kiln 12 flows, a film separating device is provided to selectively separate and remove water vapor, and a circulation path is provided to join a part of dry gas that water vapor is separated and removed from the mixed fluid into heat air and circulate the dry gas.
